Tamatar ka Achar

Use the same weight. Heat until smoking, then cool for 2 minutes before cooking; it is pungent and changes the flavour strongly.

Use the same weight. It is neutral, so add 1 tsp toasted sesame seeds for aroma.

Use the same weight. It is neutral and lacks sesame flavour; finish with a few drops of toasted sesame oil if you have it.

Use equal weight. Finely grind whole black or yellow mustard seeds in a spice grinder; yellow gives milder heat, black gives stronger pungency.

Use equal weight, crushed to a paste with a splash of water using a pestle and mortar. Adds a similar sharp bite.

Grind whole seeds finely in a spice grinder; use equal weight (1:1). Ensure it cooks through gently, as undercooked or burnt ground seeds become intensely bitter.

Crush dried leaves between your palms and add towards the end; use 50% of the weight. Gives the unmistakable maple-herb aroma without the sharp bitterness of the seeds.

Grind finely; use 50% of the weight. Adds an earthy, sharp bite, though it lacks the distinctive sweet-curry smell.

Use double the weight. Stir into hot oil just before adding wet ingredients; mimics the allium savoury background without the sulphurous edge.

Use 2 g for every 0.5 g of asafoetida. Sauté in oil until the raw smell clears; adds moisture and sweet allium depth.

Use equal weight. Stir in directly with the dry spices; delivers comparable heat and red colour.

Use 130% to 150% of the weight. Provides brilliant ruby colour with roughly half the fiery heat.

Use 75% of the weight. Gives a sharp, clean pungency without tinting the sauce red.

Use 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.

Use 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

Use 180% of the weight of compressed tamarind; soak in three times its weight of boiling water for 15 minutes, knead, and strain out the thick pulp.

Use 35% of the weight dissolved in two tablespoons of warm water. Provides sharp tang, though the resulting sauce will be lighter in colour.

Use equal weight, added right at the end of cooking. Adds sharp acidity without the deep brown hue or pulpy thickness.

Use 50% of the weight. Mimics turmeric's warm, earthy, rhizome background, but provides none of the golden-yellow colour.

Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.

Use equal weight whole. Fry in hot oil or ghee as tempered spice; gives a richer red colour with slightly milder heat.

Use 50% to 70% of the weight. Stir into the oil with ground spices; distributes heat evenly throughout the dish without whole chilli skins.

Use 100% of the weight. Soak for at least 1 hour; takes about 10 minutes longer to cook through and has a marginally earthier flavour.

Use 100% of the weight. Reduces cooking time by about 10 minutes and breaks down softer, giving a smoother consistency rather than distinct grains.

For tempering or tadka only: use 70% of the weight. Browns faster in hot oil, providing a nutty, crunchy bite.

Use equal weight. Needs longer soaking and cooking; the dark skins impart an earthy flavour and greyish-black hue unless thoroughly rubbed off.

Use equal weight when tempering (tadka). Provides a comparable nutty, crunchy texture in hot oil, though grains are slightly larger.

Use equal weight for batters or dals. Ferments and cooks faster, producing a lighter, less sticky, and less viscous consistency.

Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.

Use the same weight. They are milder and larger; fry a few seconds longer until they pop. The finished dish will have less pungency.

Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
